Wafer Triple Eccentric Butterfly Valve

Product Description

Driving Mode: Manual Structure: Three-Eccentric Sealing Valve Stem: Normal Working Temperature: High Temperature (T>450°C) Valve Body: Casting Size: 2"~48" Ends: RF, Rtj, Sw, Bw Trademark: FYV Origin: China Connection Form: Flange Seal Form: Force Sealed Work Pressure: High Pressure (10.0mpa< Pn <80.0mpa) Material of Seal Surface: Soft Sealed Application: Industrial Usage, Water Industrial Usage, Household Usage Pressure: 150lb-300lb Op.: Manual, Pneumatic, Electric, Gear Specification: CE, SGS HS Code: 8481804090 The triple eccentric Butterfly Valve, which makes use of a metal seat, is therefore able to withstand a greater amount of pressure, compared to resilient seated butterfly valve. The seal of the eccentric disc could be either metal/Graphite multi-layer design, or fully metal-to-metal design. The multi-layer design could achieve zero leakage and simple maintenance, while the metal-to-metal design is more reliable in higher temperature and pressure. Basically speaking, triple eccentric butterfly valve is both applied in shutoff or throttling service.
Flanged butterfly valves have longer face-to-face dimensions and stronger structure, compared with wafer or lug type butterfly valves. The machining process is therefore more complicated than that of wafer or lugged butterfly valves. For butterfly valves size larger than 24", flanged end is recommended for longer service.
